  <div>
   <p>Before performing backup, you need to associate the resources to be protected with a specified SLA. The system protects the resources and periodically executes backup jobs based on the SLA. You can perform a backup job immediately through manual backup.</p>
   <div class="section">
    <h4 class="sectiontitle">Precautions</h4>
    <ul>
     <li>Copies generated by manual backup are retained for the period defined in the SLA.<p>If the protection policy selected during manual backup is not defined in the SLA, the generated backup copy will be retained permanently.</p></li>
     <li>If a replication or archive policy has been defined in the SLA, the system will perform replication or archiving once based on the SLA when you perform manual backup.</li>
     <li>During manual backup, the parameters (except <span class="uicontrol"><b><span><strong>Automatic Retry</strong></span></b></span>) defined in the SLA, such as <span class="uicontrol"><b><span><strong>Rate Limiting Policies</strong></span></b></span>, are applied to the manual backup job.</li>
